you can utilize line of code in fragment want check if drawer closed or not:

drawerlayout mdrawerlayout = (drawerlayout)getactivity().findviewbyid(r.id.drawer_layout); listview mdrawerlist = (listview) getactivity().findviewbyid(r.id.list_slidermenu); if (!mdrawerlayout.isdraweropen(mdrawerlist)){ system.out.println("the drawer closed!"); }

basically calling layout activity hosting fragment.
